The purpose of this study is to explore the ways in which scientists reflect on the scientific practices, based on the premise that reflection is one of key elements for shaping scientific identities. This paper specifically considers scientists' reflections as the processes in which their senses of ethical issues and the value of science are articulated. To do so, the study developed a narrative inquiry for exploring the value of scientists' stories. Fourteen professional scientists' stories were collected in the context of the stem cell research, in ways that foreground their reflections on current scientific practices and the surrounding socio-cultural conditions. As for ethical issues, scientists' stories were analysed in terms of four claims regarding the themes of bioethics, integrity, scientific issues and communication. Furthermore, scientists' reflections on the value of science were analysed in relation to the elements of nature of science. Based on the results, discussion focused on the value of science stories as an instrument with which to guide students into the enculturation in the practices of scientific culture.

본 연구는 우리나라에서 어린이 청소년을 대상으로 한 독서 프로그램을 개발하는데 도움을 주기 위해 'Stories from the Web(SFW)'을 조사 분석하였다. 영국의 공공도서관은 정보화시대에 인터넷에 익숙한 어린이 청소년을 위해 웹방식의 새로운 독서 프로그램인 SFW를 개발하여, 유아(0세)부터 14세 청소년들에게 활용시키고 있다. SFW프로그램은 어린이 청소년들이 인터넷상에서 직접 독서를 할 수 있게 만들지 않고, 이들의 독서에 대한 흥미를 유발시켜 공공도서관을 방문하여 독서를 하게끔 유도하고 있다.

The current research aims to identify the effectiveness of a training program based on digital stories to develop writing skills for students with learning difficulties. The research sample consisted of (12) students with learning difficulties in the fifth and sixth grades, who were chosen intentionally. The results showed the effectiveness of the program and the maintenance of this improvement over time as results showed that there were statistically significant differences at the level (α = 0.05) between the two measurements, before and after, in favor of the post-measurement. The results also showed that there were no statistically significant differences at the level (α = 0.05) between the post and follow-up measurements on the writing skills scale. This indicates the long-term impact of the program. The researchers recommend the need to expand educational programs' adoption of digital stories to develop the skills of students with learning difficulties.

The purpose of this study is to investigate effects of instruction with stories on elementary school students' science learning and memory. For the purpose, this researcher sampled 3 classes in their 3th grade from an elementary school. Out of the three classes, two were designated as the comparative group consisting of 70 students and the other, the experimental group, 32 students. The former group was applied instruction treatment under the 7th national curriculum of education. The other group was instructed with a story book that contained stories students already knew which were somewhat rearranged to comply with contents of a relevant curricular course. Results of the study can be described as follows. First, academic achievement test was made immediately after the treatment to show that the experimental group was significantly higher in scores for memory and understanding in the section of 'Finding Constellations' that the other group. Second, the two groups' academic achievements in relation to the section, 'Finding Constellations' were tested 3 months after the treatment to show that the experimental group was significantly higher in scores for memory and understanding than the comparative group. Such achievements within the groups were tested 3 months after the treatment to find that both of the two groups didn't show statistically significant differences.

Elementary school pupils frequently have difficult acquiring creative writing skills, i.e. how to develop the idea to be expressed, how to compose the materials of the outcome or contents. In this paper, we focus on the problems of how to support creative writing work to arrange materials in order to formulate ideas as the stories develop. the stories develop. The basic ideas behind the method are that(1) a basic story is automatically generated by GA-based operations and shown to a user as sequences of pictures, (2) IGA(Interactive Genetic Algorithm) is used to evaluate and select a preferred story, (3) the results are combined with previously stored stories using case-based techniques. Based on these ideas, we have developed a computer supported environment for this purpose and conducted related experiments.

Structures in seismic regions are designed to dissipate seismic energy input through inelastic deformations. Structural or component failure occurs when the hysteretic energy demand for a structure or component subject to an earthquake ground motion (EQGM) exceeds its hysteretic energy dissipation capacity. This paper presents a study on identifying the hysteretic energy demand and distribution throughout the height of regular steel moment resisting frames (SMRFs) subject to severe EQGMs. For this purpose, non-linear dynamic time history (NDTH) analyses were carried out on regular low-, medium-, and high-rise steel SMRFs. An ensemble of ninety EQGMs recorded on different soil types was used in the study. The results show that the hysteretic energy demand decreases from the bottom stories to the upper stories and for high-rise structures, most of the hysteretic energy is dissipated by the bottom stories. The decrease is quite significant, especially, for medium- and high-rise structures.

Followings are the analysis of 578 fire accidents occurred at Specific Building In 1995. Fire frequency had been slightly decresed since 1992. In regional, fire accidents in Seoul and Ulsan were higher than the average. Occupational fire frequency order was apartment, factory, buildings over six stories and market place. In addition, the order of life loss was buildings over six stories, apartment and factory. And property loss totaled six times higher than that of Fire Department. Among the causes of fire, electrical fire formed 44.8%, from which we can assume that there were some problems in the investigation of fire causes.

The fact that the major cases of life casualties are from smoke in the fire accidents and the expected steep increase of skyscrapers, huge spaces, multiplexes and huge scaled underground spaces demand establishment of efficient smoke countermeasure. The field experiments on two high buildings of 20 stories and 21 stories are carried out to evaluate the field performance of pressure differential systems for smoke management and the results of experiments are presented.

이 연구는 안구운동 추적기법을 활용하여 6학년 초등 과학 교과서 '과학 이야기'를 읽을 때 학생들의 읽기 과정을 분석하였다. 이 연구에 사용된 과제는 2009 개정교육과정 6학년 1학기 과학 실험본 교과서에 수록된 3개의 '과학 이야기' 글이고, 연구 대상은 서울 G 초등학교 6학년 학생 22명이었다. 참가자들은 중간 글 - 긴 글 - 짧은 글 순서로 3개의 글을 읽고, 각 글에 대한 이해도를 평가하는 9개의 문제를 풀었다. 이해도 결과 및 성취도 결과를 바탕으로 참가자들을 상위 집단, 중위 집단, 하위 집단의 3개의 그룹으로 나누었다. 연구결과, 상위 집단과 하위 집단의 안구운동 특성은 다음과 같은 차이를 보였다. 고정 수는 상위 집단이 하위집단보다 높았으며, 고정시간은 상위 집단이 하위집단보다 낮았다. 회귀 수는 상위집단이 하위집단보다 높았으며, 회귀시간은 상위집단이 하위집단보다 낮았다. 문장별 고정 수 및 평균 고정 시간 분석 결과, 상위집단이 전체 글의 주제나 주요 원리를 담고 있는 핵심 문장(key sentence)을 더 오래 살펴보았음을 알 수 있었다. 시선 흐름 및 사후 면담 분석 결과, 상위 집단은 문장 간 회귀가 많았으며 글의 핵심이 되는 부분이 어디인지 알고 그 곳에 특히 주의를 기울였다. 반면 하위 집단은 대부분 회귀 없이 순차적으로만 글을 읽었고, 일부 학생은 정상적인 범위를 벗어난 도약을 보이기도 하였다. 또한 학생들의 문제 풀이 방식에서도 집단 간 차이를 찾을 수 있었다. 이상을 종합하면 고정과 회귀가 많고 평균 고정 시간이 짧은 읽기방식이 과학 이야기 이해도와 관련이 있으며, 문장 간의 빈번한 회귀, 충분한 핵심 탐색 과정, 효율적인 주의 배분, 글에 대한 높은 이해력, 집중력을 보이는 학생이 과학이야기 이해도가 높았다. 교과서에 사용된 단어나 문장 또한 과학이야기 이해도에 영향을 미치고 있음을 알 수 있었다. 이 연구는 기존의 과학 읽기 연구들과 비교하여 초등학생의 과학 읽기에서 어떠한 경향이 나타나는지 탐구하였고, 이 연구의 결과를 활용하여 과학 읽기에 어려움이 있는 학생을 위한 프로그램이 필요함을 제안하였다.
